The Wonderlic test is a shorter version of a basic IQ test - it isn't exactly an IQ test but is very similar. It isn't important for most positions. 32 is a good score. You don't base an IQ test on %.
Here are IQ score definitions:
- 115 to 129 - Above average; bright
- 130 to 144 - Moderately gifted
- 145 to 159 - Highly gifted
- 160 to 179 - Exceptionally gifted
- 180 and up - Profoundly gifted
200 is the max and has been scored very few times in history. 130 is considered moderately gifted and that is only 65% of 200. 145 is highly gifted and by most is rated genius, and that is 72%.

When players score good it shows a few things...
If a player gets a good score it shows that they prepared for the test, or they are generally intelligent. This is a good thing for obvious reasons - if they prepared for the test it shows they care about something as small as the test. Immagine how they'll prepare for games. If they are generally smart they will probably make better on field decisions - how many times do you see a player not run out of bounds when they should when on a 4th qtr comeback drive with barely any time left?
If a player receives a bad score it can mean they didn't try at all, or they might not be the brightest. This can be bad for obvious reasons as well - If they didn't try, that attitude might translate to football. They might quit on plays or take plays off. If they aren't very smart then it can affect games - they may not run out of bounds on a 4th qtr comeback drive when they should. They may not think about lining up the hash marks to make it easier on the kicker for the last second field goal attempt if the wind is blowing crazy to one side. They may not think about how they should be acting in public. They may not think about the fact that they shound not say anything about a bomb in an airport (Aldon Smith). They may truely be idiotic...
The Wonderlic DOES have some value in evaluating potential NFL players...
